Everything works! fantastic! Thanks again! Just an idle thought: Dealing with the backend api is always a little rough the first time out. It's an awfully big job, but ISTM that the C language backend api could use some expansion. Perhaps it could get it's own chapter, with sections for SPI, Datums, triggers, composites, arrays, etc. "34.8 C-Language Functions" is overlong and not very well organized IMO. I certainly don't have time to work on ATM though. merlin -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
